So far, the progress on the subfile_open system call is opening the  
basefile (using a modified open system call), getting necessary  
information about it that I will need later (mode flags,  
subfile_dir_inode, etc), and then just returning the fd for the  
basefile (this will ultimately be changed to the subfile fd  
obviously). Creating/opening the subfile file has not started yet.  
This is mainly due to the time constraints that I had to deal with  
that I stated in the earlier post about the status of the project.
